"Riveting and poignant . . . The Winter Fortress metamorphoses from engrossing history into a smashing thriller . . . Mr. Bascomb's research and, especially, his storytelling skills are first-rate."--The Wall Street Journal "Weaving together his typically intense research and a riveting narrative, Neal Bascomb's The Winter Fortress is a spellbinding piece of historical writing." -- Martin Dugard, author of Into Africa and co-author of the Killing series In 1942, the Nazis were racing to complete the first atomic bomb. All they needed was a single, incredibly rare ingredient: heavy water, which was produced solely at Norway's Vemork plant. Under threat of death, Vemork's engineers pushed production into overdrive. If the Allies could not destroy the plant, they feared the Nazis would soon be in possession of the most dangerous weapon the world had ever seen. But how would the Allied forces reach the castle fortress, set on a precipitous gorge in one of the coldest, most inhospitable places on earth? Based on a trove of top-secret documents and never-before-seen diaries and letters of the saboteurs, The Winter Fortress is an arresting chronicle of a brilliant scientist, a band of spies on skis, perilous survival in the wild, Gestapo manhunts, and a last-minute operation that would alter the course of the war. "A taut and peerlessly told adventure story full of thrills, derring-do and heart-stopping tension." -- Seattle Times "Told with both historical and scientific accuracy . . . this book has rocketed into my pantheon of the top suspense-filled stories about World War II], along with The 900 Days and The Colditz Story." -- Ethan Siegel, Forbes

The story of how a desperate clandestine mission in Norway ended the Nazi dream of building the atomic bomb.

In May 1941, the Norwegian Section of SOE received a dossier warning of the dangers of a hydroelectric fertiliser plant in Norway. Vemork produced heavy water, an essential part of making plutonium for nuclear weapons. When the Germans overran Norway the entire stock had been smuggled out of the country, but the plant was intact and soon producing heavy water again, destined for the German nuclear programme. Despite the difficulties of getting to and operating in such a remote, hostile area, SOE decided it had to destroy the plant. Six ski-borne commandos had the task of slipping past 300 heavily armed guards and passing through a ravine the Germans thought impassable. Fully illustrated with stunning new commissioned artwork, this is the thrilling story of the daring Norwegian-led SOE raid that prevented Hitler from building an atomic bomb.

“An exciting and dramatic episode.”—Library Journal “Cliff-hanging suspense.”—Christian Science Monitor Assault in Norway is the classic account of a legendary raid on the Nazi war program. By 1942 Germany had a seemingly insurmountable lead over the Allies in developing an atomic bomb. Contributing to this situation was its access to a crucial ingredient: “heavy water,” found in great abundance at a fortresslike factory in occupied Norway. Allied hopes of stalling the Nazi nuclear program soon focused on sabotaging the cliffside plant—a suicidal mission. But a team of brave Norwegian exiles, trained in Britain, infiltrated their homeland and, hiding in the wilds, awaited the opportunity to launch one of the war’s most daring commando raids. Basing his gripping narrative in large part on interviews with the commandos themselves, Thomas Gallagher recounts in vivid detail the planning and execution of Operation Gunnerside. Assault in Norway recalls the intrigue found in such wartime classics as David Howarth’s We Die Alone and The Sledge Patrol, and the mission it recounts inspired the 1965 Hollywood film The Heroes of Telemark.

Heavy water (deuterium oxide) played a sinister role in the race for nuclear energy during the World War II. It was a key factor in Germany's bid to harness atomic energy primarily as a source of electric power; its acute shortage was a factor in Japan's decision not to pursue seriously nuclear weaponry; its very existence was a nagging thorn in the side of the Allied powers. Books and films have dwelt on the Allies' efforts to deny the Germans heavy water by military means; however, a history of heavy water has yet to be written. Filling this gap, Heavy Water and the Wartime Race for Nuclear Energy concentrates on the circumstances whereby Norway became the preeminent producer of heavy water and on the scientific role the rare isotope of hydrogen played in the wartime efforts by the Axis and Allied powers alike. Instead of a purely technical treatise on heavy water, the book describes the social history of the subject. The book covers the discovery and early uses of deuterium before World War II and its large-scale production by Norsk Hydro in Norway, especially under German control. It also discusses the French-German race for the Norwegian heavy-water stocks in 1940 and heavy water's importance for the subsequent German uranium project, including the Allied sabotage and bombing of the Norwegian plants, as well as its lesser role in Allied projects, especially in the United States and Canada. The book concludes with an overall assessment of the importance and the perceived importance of heavy water for the German program, which alone staked everything on heavy water in its quest for a nuclear chain reaction.

Norwegian commandos aim to destroy the Nazi nuclear program in this World War II thriller of action and espionage by a New York Times–bestselling author. Based on the true story of Operation Gunnerside February 1943. Both the Allies and the Nazis are closing in on attempts to construct the decisive weapon of the war . . . Kurt Nordstrum, an engineer in Oslo, puts his life aside to take up arms against the Germans as part of the Norwegian resistance. After the loss of his fiancée, and with his outfit whittled to shreds, he commandeers a coastal steamer and escapes to England to transmit secret evidence of the Nazis’ progress towards an atomic bomb at an isolated factory in Norway. There, he joins a team of dedicated Norwegians in training in the Scottish Highlands for a mission to disrupt the Nazis’ plans before they advance any further. Parachuted onto the most unforgiving terrain in Europe, braving the fiercest of mountain storms, Nordstrum and his team attempt the most daring raid of the war, targeting the heavily-guarded factory built on a shelf of rock thought to be impregnable, a mission even they know they likely will not survive. Months later, Nordstrum is called upon again to do the impossible, opposed by both elite Nazi soldiers and a long-standing enemy who is now a local collaborator—one man against overwhelming odds, with the fate of the war in the balance, but the choice to act means putting the one person he has a chance to love in peril.
